SAN FRANCISCO (KTVU) - Safety changes are being implemented at a busy intersection in the Marina District after two boys were hit by a car Wednesday.
A 30-year-old woman was arrested on suspicion of driving under the influence of alcohol or drugs after striking the two 12-year-old boys in a crosswalk at Buchanan and Bay streets, a police spokesman said.
The woman was identified as Kirsten Andereck of San Francisco.
The boys suffered life-threatening injuries including broken bones and head trauma and were being treated at San Francisco General, but are expected to survive.
According to SFPD Capt. Greg McEachern, the boys were thrown 40 feet in the air from one crosswalk to another. Their shoes were knocked off their feet, and their backpacks and sports drink were tossed into the air.
Andereck was driving a white Volkswagen Tiguan SUV and stayed at the scene of the collision.
Neighbors say cars speed down this street often and they've asked for more patrols or a stop sign.
San Francisco Supervisor Mark Farrell said, "This is simply intolerable. We're going to be doing everything we can but as more and more people live in our city - as our streets are more crowded with people walking, biking, driving - we need to be so careful as residents."
On Thursday morning San Francisco supervisor Mark Farrell told KTVU that stop signs will be added to the intersection within the next several days.
He says plans have also been under consideration for re-paving and re-striping of the area.
Farrell adds driving under the influence is unacceptable and drivers will be prosecuted.
